The Best Laptop Power Banks You Can Buy Today

Power banks are available in a variety of sizes and forms to accommodate a wide range of needs. A power bank’s power output, capacity, ports, and TSA approval all contribute to its suitability for a particular application. However, the essential characteristic to consider when shopping for laptop power banks is the output power.

Because each laptop model requires a different amount of power output, it is critical to check the power input specifications of your laptop prior to purchase. For example, MacBooks consume anywhere between 29W and 96W of power, depending on the model. Moreover, laptops with faster processing speeds and bigger screens often use more input power than ultraportable laptops, which in turn use less input power.

If you choose a power bank that is insufficient for the power requirements of your laptop, charging will be prolonged or will not occur at all. Bear in mind, that just because the power bank can deliver a high amount of power does not guarantee that the laptop will charge quickly.

When deciding how to charge a laptop, it’s important to consider the ports available on the device. To charge a laptop optimally, your port must be capable of transferring the necessary amount of power. When compared to USB-A, USB-C is more capable of accomplishing the job required. If your laptop does not have a USB-C port, you should opt for a power bank that includes both a DC cable and a port.

If you are traveling by airplane, keep in mind that your power bank should have a capacity of lower than 100Wh (about 27000mAh) and a clear label/imprint indicating the charger’s capacity (mAh and Wh).

Are you a power user in search of a versatile power bank? In that case, we recommend Omni20+. This power bank is armored to the teeth in terms of ports and power output and is considered a holy grain by some. Omnicharge has a capacity of 20000mAh and 71Wh, ensuring that you will have enough power to charge anything from smartphones to GoPros, drones, and laptops.

Apart from physical ports, the Omnicharge Omni20+ features a +10W wireless charger that is compatible with any device that supports wireless charging. While the majority of compact laptop power banks only include USB-C ports for laptops, the Omni20+ encompasses AC and DC inputs for added convenience.

The USB-C port offers a maximum power output of 60W, which is typically found on 13-inch and some 15-inch laptops. With a capacity of 20000mAh, you can charge a smartphone five times, an action camera ten times, a DSLR five times, and a 15-inch laptop once.

It is worth noting that USB-C supports Power Delivery technology, resulting in rapid charging. Furthermore, the Omni20+ is outfitted with pass-through charging to keep itself, and the devices connected to it charged at all times.

The matte finish gives this power bank a classy appearance, and the build quality is what we would expect from a well-known brand. Furthermore, with a weight of 1.35 lbs (611g), it is very portable.

One of the best features of this product is its display. You don’t have to guess how much power your devices consume or how much power your Omnicharge provides. The OLED display allows you to monitor the power levels of your device better and know what you need to keep fueled throughout the day.

The company paid close attention to detail, assigning a dedicated button to each USB-A button, which is very practical.  As previously stated, the Omnicharge Omni20+ has a 71Wh capacity and is TSA-approved so you can bring it into the flight without prior permission.

Although not as famous as other brands in this list, Renogy, delivered a sound product in the Renogy 72000mAh. It’s one of the few power banks that’s been made primarily for laptops. With its high-end capacity, it can power almost all laptop models, with the exception of those that operate with a DC current of over 62.7W.

One of the most appealing features of the Renogy 72000mAh is the fact that it comes with two DC outlets; a Laptop output port, and a cigarette lighter port.  So if you’re into activities that require the use of two laptops at the same time, through a car inverter to laptop adapter, this is could be one of the best alternatives. Besides the 2 DC outlets, it also features one USB-A port, two USB Type C ports (one of these supports PD), and one 12V/15A cigarette lighter port for small medical equipment or devices with an extra car power inverter.

3. Goal Zero Sherpa 100PD 

GoalZero Sherpa 100PD

  • Capacity: 25600mAh
  • Max Output: 60W
  • Ports: 2 USB Type A, 1 USB Type C
  • Charging Time: 3 Hours
  • Weight: 22 oz / 635 g
  • mAh/$: 166

Check price on Amazon.com

Or buy on GoalZero.com or on BestBuy.com

If you’re looking for a high-quality, compact power bank with an adequate number of ports, the Goal Zero Sherpa 100PD is a decent choice.

This lithium-ion power bank features a capacity of 25600mAh and a power output of 94.7Wh. This amount of energy is enough to charge a smartphone seven times, a tablet three times, and a laptop 1.5 times. Moreover, if you’re wondering whether you’re allowed to bring the 100PD on a flight, the answer is yes, as it’s under the TSA’s limit of 100Wh.

This power bank has three ports: two USB-A (12W) ports and one USB-C (60W) port.

Two USB-A ports allow you to charge two devices simultaneously, such as fitness trackers, GPS devices, and micro/lightning phones. If your laptop is equipped with a USB-C port, you can charge it by connecting it to the USB-C port on the power bank.

GoalZero Sherpa Charging Ports

It’s critical to keep in mind that this port delivers a maximum of 60W, which means that charging the laptop should be done when it’s not in use. However, if you have an ultraportable laptop, such as a 13-inch MacBook, with a low power requirement, you can charge and run the laptop concurrently.

The Sherpa 100PD features Power Delivery technology for quick charging via the USB-C port. In summary, Power Delivery technology enables the power bank and the device it charges for communicating with one another and determining the maximum amount of power that can be drawn from the charger to the device in order to speed up the charging process.

Another fascinating aspect of Power Delivery is that it enables power to flow in both directions without regard for circuit or connection orientation. So, for instance, if you use a USB-C charging cable to connect two smartphones that support Power Delivery, one can charge the other and vice versa.

To ensure safety, Goal Zero has regulated all three ports on this power bank to ensure constant flow without overheating, short-circuiting, or overcurrent.

Furthermore, if your devices support wireless charging, you can enjoy the convenience of this feature with Sherpa 100PD without the need for cables.

The gleaming and elegant Sherpa 100PD is a surefire way to win your heart when it comes to appearance. The body of this power bank is plastic, but it would seem to be aluminum, and it weighs 1.4 pounds.

This material has a number of advantages and disadvantages, and the customer must decide whether it is beneficial or detrimental. While a plastic power bank is lighter than an aluminum one, the aluminum body is more impact-resistant and has the potential to survive in harsh environments. 

Unlike some power banks, which display the remaining charge via green and red LED lights, this power bank features an LCD display that shows the exact amount of juice remaining in the battery, which is an added benefit of this product.

4. Crave PowerPack 50000mAh

Crave PowerPack 5000mAh

  • Capacity: 50000mAh
  • Max Output: 100W
  • Ports: 2 USB Type A, 2 USB Type C
  • Charging Time: 4-5 Hours
  • Weight: 32 oz / 907 g
  • mAh/$: 200

Check price on Amazon.com

Or buy on CraveDirect.com or on Ebay

This is a highly versatile external laptop battery that will charge almost all laptop models. It can deliver up to 100W via its main USB type C port, which is more than enough even for power-hungry MacBook PROs.

In terms of port variety the Crave PowerPack features the following:

  • one 60W PD USB type C port
  • one 100W PD USB type C port
  • two QC 3.0 USB type A ports

Crave PowerPack Ports

You can use it to charge 4 different devices at the same time. When all ports are active, it can supply a maximum of 123W in total. So the maximum amount per each individual port will drop slightly as compared to that port being used just by itself. 

This portable charger also comes with a wall charger, which is quite rare for a power bank. Generally, you’ll need to have your own charger for the power bank you’re buying. Using the included charger, you can top up the Crave PowerPack in 5 to 6 hours, which is a very good time given its large capacity. 

Given the fact that it has a total capacity of 185Wh, which is way over the maximum admitted capacity of 160Wh, this power bank cannot be taken on planes. You’ll need to limit yourself to other means of travel if you’re planning on taking it with you on trips.
